How to check event scheduler status mysql

Question

In MySQL, we can enable the event scheduler by following query:

SET GLOBAL event_scheduler = ON;

Similarly, to turn off the scheduler:

SET GLOBAL event_scheduler = OFF;

But, Is there any query/way to check the status of this event_scheduler whether it's on or off?

Answer 1

Use SHOW VARIABLES

SHOW VARIABLES
WHERE VARIABLE_NAME = 'event_scheduler'

Answer 2

This should also work:

select @@global.event_scheduler = 'ON' 

That is a little easier to use in a stored procedure, where you might want to know if it is ON before turning it on. Note that I tested this on MySQL 5.7 after turning on Event_Scheduler either with ON or 1. In both cases, querying the variable returns 'ON'.

Also, note the quotes are used for querying, but not for setting the variable. A little mysql weirdness for you.
